Expansion Card resizes due to big image

I am using a big portrait Image for background in the Expansion Card and it looks like that in the collapsed state, it Expands based on the size of the image.

this is the expansion card with big image. When I use a Square one, it looks as should:

If you wrap the image you put in the background with the container widget and give the height value, you can solve the problem.

ExpansionCard(

      background: Container(
        height: 400,
        child:Placeholder(),
      ),
    ),
